We're dividing 85139 by 50 
We want to divide 85139 by 50.

Going ahead to step 1:
The number 50 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 50

Advancing to step 2:
50 can be fit into 85 1 times, resulting in a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 50 from 85 leaves us with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 50

Going ahead to step 3:
351 divided by 50 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 350 away from 351, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 50

Moving on to step 4:
When dividing 13 by 50, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 50

Let's proceed to step 5:
139 divided by 50 is 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 1702.0
Subtracting 100 from 139 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 6:
When dividing 390 by 50, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 1702.7
If we subtract 350 from 390, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
400 divided by 50 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1702.78
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1702.78
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1702.78
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1702.78 with a remaining 0.0.
